WP-3D Data Info

File prefixes from data download are listed below. The file contents are specified and the measurement is described briefly. For more details, see the header of the data file.

Time parameters

Time: Most of the P-3 data is time-aligned to AOCTimewave, which is 1 second time resolution in integer seconds.
It starts at the time the aircraft takes off, and ends at landing. Many of the parameters are on this time base.
Here are the exceptions.
CH2O: TimeStart_CH2O / TimeStop_CH2O (2 minute measurement)
VOCsGCFID: StartTime_GCFID / StopTime_GCFID (measurement every 15 minutes)
VOCsWAS: TimeOpen_WAS (variable intervals)
NAerosol: TimeStart_NAerosol / TimeStart_NAerosol (10 second averages)
JValNCAR: jVALTimewave (10 second data)
